METALLIC RAILWAY-TIE.

Specification of Letters Patent.

Patented Sept. 1, 1908.

Application led March 28, 1908. Serial No. 423,857.

To all whom it may concern:

Be it known that I, GEORGE T. BRIDWELL, a citizen of the United States of America, residing at the city and county of Denver and State of Colorado, have invented a new and useful Metallic Railway-Tie, of which the folowing is a specification.

he same time act cooperatively with it in the support of Second, to provide a flexible tie yield under heavy fast moving cient to prevent crystallization. to provide a metallic out of any suitable sheet metal or if desired Figure l, is a longitudinal vertical sectional view through a metallic railway tie constructed in accordance with my invention, showing the rails secured to spring saddles which are bolted to the bottom of' the tie. Fig. 2, is a plan view of the same. Fig. 3, is a perspective view of the tie, showing the recesses in the sides of the tie, in which the rails lie. Fig. 4, isa perspective view of the form of tie employed where a switch occurs. Fig. 5, is a perspective view of one of the rail-supporting saddles. Fig. 6, is a perspective view of one of the rail clamps. And 4ig. 7, is a sectional view of a modiiied form of tie, amodified form ofsaddle being shown in comiection therewith.

Similar numerals ol' reference refer to simi lar parts throughout the several views.

Referring to the drawings, the numeral l, designates the shell or body of my tie. This shell or body portion comprises a rectangular trough shaped section of the length of the standard tie, and of suflicient depth and width to form a firm holding foundation for the rails and trains. Th bedded in the road bed with their horizontal members 2, down, and their sides extending l siliently yield'under passing ese ties are eml9 vertically upward. The top edges of these sides are provided with rail holding recesses 3, which are adapted to receive the lower flange of the rails, but where these ties are used at switches these rail holding recesses can not be used. Consequently my invention contemplates this box-shaped tie made both with and without the rail holding repreferably with them, as

bottom portion as well as the central portion of my tie may be made in any desired manner, but I preferably provide the bottom portion with a number of through which Wabottoms of all e foot portions ofthe saddle rest on the bottom of the tie and are secured there b any suitable means, preferably by bolts or The top portion of the saddle is permit the saddle to reheavy loads, but permit the rails the sides of the tie to not to such an extent as to are intended solely as abutment guides for the sides of the rails. The rails are secured to the tops of the spring saddles by clamping plates l0, which are bolted to the foot pory iio cap sc rews 11, which are threaded in the x cured to said channel beam, in line with said clamping plates, and are screwed down recesses, comprising foot portions from whlc against the top surface of the rail fiange, extend upright members which terminate in which acts to cause these clamping plates to beai' with a resilient clamping pressure against the tie flange of the rail. A

ln Fig. 7, l have illustrated a modification of the tie, and in this form of tie the central ortion of the bottom is elevated as shown at 12, to form a chamber having abrupt, verti-` cal ends 13, which act as abiitments to prevent the tie from slipping lengthwise under heavy loads, especially on curves where the the bottoms of the said recesses; plates secured upon the foot portions of the saddles, which extend above the tops of the saddles, and terminate in inwardly projecting ends,

and set screws in said inwardly-turned ends. 2. 1n a railway tie as specified, the combination with a channel beam having oppositely-arranged rail receiving recesses in its side members, of resilient saddles secured to the bottom of the beam, in line with the recesses, the tops of the saddles being above the bottoms of the recesses; rail clamps secured upon the lower ends ofthe saddles, and extending above and over ,the tops of the saddles, and set screws in the upper end of the clamps.

3. ln a railway tie as specified, the combination with a channel beam having oppositely positioned rail receiving recesses in its tracks are given an inclined pitch, which tends to cause them to creep laterally upon the road bed. When the tie is set, the material composing the road bed fills the chamber', and the ends of the chamber contacting with this body of material holds the tie from endwise movement, as above stated. ln connection with Fig. 7, l have also illustrated a modification in the -form of saddle, and in this form the saddle comprises foot members 14, from which extend diverging upright members 15, which terminate in horizontal rail-receiving members 16, this construction affording a more reslient support than the saddle illustrated in the otherl views.

ln Fig. 4, l have illustrated the form of tie used at points where switches occur. This tie 17, is formed with plain sides, the recesses 3, being omitted.

In operation the tie is embedded in the ground, as is customary, with the spring saddles secured in their proper places to it. The rails 1S, are then laid across the ties in the recesses of the ties on the saddle, and are clamped to the saddles by the clamping lates. rlhe rails are thus firmly bedded in 40 the recesses in the sides of the ties, and are thus firmly held against lateral movement rail receiving recesses in its side members, and are also rigidly secured to the spring sadand a raised portion in its bottom, terminatdles, which are made strong enough to resist \ing in abrupt vertical ends, of saddles sein line with said recesses, comprising foot portions which rest upon the bottom of the beam, and inclined upright members which terminate in a horizontal bridge, which is above the level of the bottoms of the rail receiving recesses; rail clamps having foot portions which rest upon the corresponding portions of the saddles, upright members which run parallel with the corresponding members of the saddles, and terminate in inwardly projecting ends; set screws in said ends, and bolts extending through the foot portions of the saddles and clamps and through the bottom of the channel beam.
